PROBLEM TO BE SOLVED: To provide a tandem vane type compressor capable of restraining enlargement by minimizing the number of components as much as possible.SOLUTION: A valve chamber 51 communicated with a second gap K2 that is an emission pressure region is formed on a center plate 17, and an on-off valve 50 comprising a valve body 53 for opening/closing the valve chamber 51 and an energization spring 54 for energizing the valve body 53 in a direction of opening the valve chamber 51 is provided to the valve chamber 51. Furthermore, a communication passage 60 branched toward a first back pressure chamber 31c and a second back pressure chamber 32c from the valve chamber 51 and communicating the valve chamber 51 with the first back pressure chamber 31c and the second back pressure chamber 32c is formed on the center plate 17, and refrigerant gas existing in the second gap K2 is introduced to the first back pressure chamber 31c and the second back pressure chamber 32c via the valve chamber 51 and the communication passage 60. |
